Title: Transmission system for digital signal
Inventor: SUGIYAMA TAKATOSHI
IPC: H04L1/00
Filed: 1990-07-23
Abstract: PURPOSE:To improve the anti-interference characteristic by sending a signal whose required band is limited to bring an interference wave into outside of the band in response to the location of the interference wave thereby eliminating the effect of the interference wave while the same filter as a transmission band limit filter at a receiver side is used as a reception filter. CONSTITUTION:An interference wave frequency detector 13 detects a frequency component of an interference wave fed to a desired wave at a receiver side to obtain interference wave frequency information 14 representing a frequency difference DELTAf between the interference wave frequency and the desired carrier and the result is sent to a sender side band limit filter 5 and a receiver side band limit filter 7. The frequency characteristic is set in the transmission reception filters 5,7 based on interference wave frequency information (DELTAf) so as to limit the desired band at one side with the interference wave in existence therein by a frequency fc+fv or fc-fv. Thus, the frequency band of the interference wave is suppressed by the band limit filter at the receiver side and band limit is implemented in advance even on the sender side to utilize the transmission power effectively.

Title: Manufacture and module of photoelectric device
Inventor: SUMITOMO KENJI
IPC: H01S5/042
Filed: 1986-08-22
Abstract: PURPOSE:To eliminate a waste of a component to be supplied to the assembly of a package or the like and to reduce the frequency of occurrence of a reject by a method wherein the characteristic of a light-emitting device is measured in the form of a module so that only the module judged to be good is assembled into the package. CONSTITUTION:During a life test of a laser diode a large quantity of heat is generated from a laser diode chip 8. A substrate 5 receives this heat through an intermediary of an adhesion material such as solder or the like. The heat is quickly conducted to the whole region of the substrate 5 so that the heat can be dissipated to a heat sink 10 for mounting a module 4 while the characteristic is measured. Therefore, the life test, etc. can be completed without any trouble. The life test of this module 4 can be executed in the form almost similar to the state that the laser diode chip 8 is assembled into package. Only the chip which has been judged to be good is assembled into the package whose processing cost is high. The final inspection of the characteristic can be completed at the initial assembling stage. Through this constitution, it is possible to reduce the occurrence of a reject in the form of a finished product and to improve the yield.

Title: Method for checking energizing of motor
Inventor: SEKIYA SHIGENOBU
IPC: H02P7/00
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain a method by which the disconnection and short-circuiting of the armatures of separately excited DC brushless motors can be checked, without rotationally driving the motors. SOLUTION: Separately excited DC brush motors ML and MR can be controlled independently, because armature current control circuits which supply electric currents to armatures 61 and field current control circuits which supply electric currents to fields 62 are constituted in separate systems, except for a shared battery B2. The disconnection and short-circuiting of the armatures 61 are checked by supplying armature currents, in a state where the field currents are substantially controlled to zero and comparing detected armature currents with a reference value. During the check, therefore, the occurrence of working sounds can be prevented by stopping the rotation of the motors ML and MR, and in addition, the influence on a section to be driven can be avoided by preventing the unwanted rotation of the motors ML and MR.
